CONTROL AND MIXING APPARATUS FOR HOT AND COLD WATER Filed March 13, 1954 ATTORNE UNITED STATS CONTROL AND MIXHNG HOT APPARATUS FUR COLD WATER Charles A. Stumm, Huntington Park, Calif.

Application March 13,

Claims.

My invention relates to control and mixing apparatus for hot and cold water, and more particularly to an apparatus especially designed for use in beauty parlors, barber shops and other places where it is desired to have, in combination with a wash bowl or the like, an apparatus by means of which it is possible and convenient to readily control the flow, as well as the temperature, of the water with a single member, manually operated, together with a shower or spray head connected and mounted for manual movement and manipulation whereby to get the best results with the greatest'convenience to the patron.

Among the salient objects of my invention is to provide in such an apparatus a valve mechanism within which there is a valve element for controlling the inflow of cold or hot water selectively to a mixing chamber, with a control valve element simultaneously operated for control of the discharge from said apparatus; to provide in connection with the discharge from said apparatus a shower or spray device connected for manual manipulation and movement, said connection being such as to permit the free movement of said shower or spray device; to provide in combination therewith a holding seat for said shower or spray device, whereby the same is normally held over the bowl in a way not to be accidentally misplaced or moved so as to discharge water outside of the bowl proper.

Other objects and advantages will be disclosed in connection with the following more detailed description of one practical embodiment of my invention, shown on the accompanying sheet of drawings, which I will now describe. In the drawing- Figure 1 is a perspective View of a wash bowl with my invention in combination therewith;

Figure 2 is a longitudinal sectional view through the control and mixing device of my apparatus;

Figure 3 is a cross sectional View taken on line 33 of Fig. 1; and

Figure 4 is a side elevation of the shower or spray device of the apparatus, slightly raised out of the holding seat.

Referring now in detail to the drawing, 5 designates a Wash bowl, to which the control and mixing device, designated as a whole 6, and the shower or spray device, designate-d as a whole 7, of my apparatus, are attached, said devices being connected by means of a flexible hose 8, whereby the shower or spray device of the apparatus can be lifted from its seat and manipulated as may be necessary to give the best results.

Referring now to Fig. 2, I will describe in detail 1934, Serial No. 715,319 (Cl. 277-7) the control and mixing device 6. A body 9, externally threaded, with a cylindrical bore therethrough, has two lateral, integral extensions to and H, to have connected therewith, from any suitable source, hot and cold water supplies for 5 supplying hot and cold water into the body 9. Into the lower end of said body is screwed a plug member l2, having a tubular extension i2 extending up into the body El, with its upper open end forming a valve receiving seat, as at l 3, said member i2 10 also forming a coupling means for the hose 8, with nut i l.

Screwed into the upper end of the body 9, is a bushing It, with packing l6, and through this bushing and packing is a cylindrical member ll, the lower portion of which is bored out to form a cha lber it, which becomes a mixing chamber around the tubular extension l2, while the inner juncture between the chamber and the solid portion of the cylindrical member l i is formed into a conical or needle valve is, positioned to seat into the end of the tubular extension l 2, as shown in Fig. l. The upper end of said member H is shown reduced in diameter, with its upper end externally threaded, as at 226, to receive a finishing member 2 l, of ornam ntal form, provided at its lower end with an internally threaded portion 222, to screw on to the upper end of the body and to rest down upon the bowl body 5, as indicated. The upper end of said finishing member ii is reduced in diameter and provided with an internally threaded portion 23, to receive the threaded upper end the body portion of the member ill, whereby as said member ii is turned by means of an ornamental operating handle Zd, said body ii is raised and lowered to seat and unseat the valve is, as will be clear from the rowing in Fig. 1. The handle 24% is secured in place on the upper end of the member El by means of a screw 25. The lower end of the member ii, in which is the chamber l 8, is provided with inlet openings 26 and 21, extending circumferentially and positioned to register with the inlets at it and l I together or separately.

Thus the cylindrical member H can be turned so as to put the openings 26 and 27 in partial register with the inlets l0 and H at the same time so as to admit both cold and hot water into the chamber it, or either can be cut oil and only the other put in open communication with said chamber l8, making it possible to get a mixture of hot and cold water, or to get all hot, or all cold water, or any mixture desired, as will be understood from the showing made in Figs.

2 and 3.

To the other end of the hose 8, is attached the shower or spray device I, the hose passing up through a bushing member or body 28, secured through the bowl body 5, and held in place by means of a nut 29, the upper end of said member 28 having therein a formed seat 39 into which the angle portion I of said shower or spray device fits and by which it is held to project out over the bowl proper. It will be understood, of course, that the shower or spray device I can be lifted from its seat 30, the hose moving freely up through the member 28 as may be necessary for the free use of the device 1.

Thus I have provided a neat and attractive device for beauty parlors, barber shops and the like, but do not limit my invention to any particular place of use or any particular embodiment, realizing that many changes can be made in the details of construction and arrangement without departing from the spirit of the invention, and it is my intention that the invention shall be limited only by the appended claims.

I claim:

1. In a control and mixing apparatus for hot and cold water, a body having a chamber therein with inlet means for connecting supply p'pes therewith for hot and cold water, a tubular out" let member extended into said chamber and having means for connecting a discharge pipe with said body and said tubular member, a cylindrical valve member rotatably mounted in said body and telescoping at its lower end over said tubular outlet member and having a part therein for seating upon and closing the upper end of said tubular outlet member, the lower end of said valve member having openings through its wall positioned to be turned into and out of register with said supply inlets to said body for selectively opening and closing said inlets, and a single handle for turning said cylindrical valve member to selectively open the inlets and also the outlet through said tubular member to the discharge pipe.

2. In a control and mixing apparatus for hot and cold water, a body'having a cylindrical chamber therein with inlet means for connecting supply pipes therewith for hot and cold water, a tubular outlet member extended into said chamber and having means for connecting a discharge pipe with said body and said tubular member, a cylindrical valve member rotatably mounted in said body and telescoping at its lower end over said tubular outlet member and forming an annular chamber around the said tubular outlet member within said cylindrical valve member, said cylindrical valve member having openings through its side wall positioned to be turned into and out of register with said supply inlets to said body for selectively opening and closing said inlets, said cylindrical valve member having therein a solid part positioned to seat upon the upper end of said tubular outlet member for closing the same, and unitary means for turning said 5 valve member to selectively open the inlets to said body and for simultaneously opening the outlet through said tubular member to said discharge pipe.

3.
